Afrotheria
|
Afrotheria (which means "wild beast of Africa") is a special group of mammals. These animals are mostly found in Africa. They include well-known animals like elephants and aardvarks. Other members are hyraxes, manatees, golden moles, elephant shrews, and tenrecs. Even though they look very different, scientists have found they are all related. This discovery was made using genetics and molecular studies.

What are Afrotherians?
Afrotheria is a scientific term for a clade of mammals. A clade is a group of living things that share a common ancestor. This means they all came from the same ancient animal. Most of these animals live in Africa today. Some, like the Indian elephant and certain sea cows, live in other parts of the world.
A Unique African Story
For a long time, Africa was like an island continent. This was from the early Cenozoic Era until about 25 million years ago. Because Africa was separated, the animals living there evolved in their own unique ways. This is why many Afrotherian groups are found mostly or only in Africa. Their shared history was only discovered recently through advanced genetic tests.
How We Know They're Related
It's hard to believe that an elephant and a tiny golden mole are related. They look so different! For many years, scientists didn't realize these animals were connected. But in the late 1990s, new ways of studying DNA and other molecules helped. These studies showed that all Afrotherians share a common ancestor. This means they are all part of the same ancient family tree. Scientists are still studying how the different Afrotherian groups are related to each other. For example, elephants and manatees seem to be close relatives. Elephant shrews and aardvarks also appear to be related.
Protecting Afrotherians
Many animals in the Afrotheria group are currently at risk of extinction. This means their numbers are getting very low. If these species disappear, it would be a big loss for the planet. It would mean losing a lot of unique genetic and evolutionary diversity.
While most Afrotherians live in Africa, some live elsewhere. The Indian elephant and three of the four types of manatees live outside Africa. Many of these species are also endangered. In the past, during the Quaternary extinction event, elephants (called proboscideans) lived on every continent except Australia and Antarctica. Hyraxes also lived in parts of Europe and Asia until relatively recently. Protecting these unique animals is important for keeping our planet's biodiversity rich.
